Ecommerce & headless commerce
We build and extend online stores on MedusaJS, Shopify and WooCommerce, with Next.js storefronts.
We separate the storefront from the backend wherever that makes shopping faster, so the technology you pay for drives your results.
Overview
A profitable online store is wired into 5 parts of your business: warehouse, accounting, carriers, marketing and customer service. That’s why we start with your processes—how an order is created, who handles it, where time and money leak today—because they shape an architecture that takes real work off your team.
We use MedusaJS when you need custom sales logic and full control over the backend, Shopify when a fast, predictable launch is the priority, and WooCommerce when the store runs alongside extensive WordPress content. We build the storefront in Next.js, React and TypeScript, so pages load fast, rank higher in search and fewer shoppers abandon their carts.
We build new stores from scratch and take over existing ones: when you already sell online, we improve the checkout, add integrations or move you to another platform with your traffic and full order history intact.
Custom modules, workflows and data migrations.
Server-side rendering, TypeScript and fast product listings.
Local payment methods, Google Pay, Apple Pay, cards and installments.
PL, EN, DE and CZ—currencies, taxes and shipping set per country.
MedusaJS, Shopify and WooCommerce each have a capability ceiling and a cost threshold. We spell out both before you sign a contract.
MedusaJS gives you full control over your store’s backend, so we can tailor the sales logic exactly to your business model. We write custom modules and automations, handle data migrations and extend Medusa Admin with the screens your team actually uses.
Shopify themes built around your brand, custom apps and connections to the systems you already use. It works best when you want a fast launch and predictable upkeep, and your sales logic stays within what Shopify supports.
WooCommerce runs your sales alongside extensive content: a blog, a knowledge base and landing pages. We build custom WordPress themes and plugins, so the site stays fast and updates roll out without surprises.
Server-side rendering, support for multiple markets and languages, TypeScript and Tailwind CSS. We keep the Next.js storefront separate from the backend, so a redesign ships quickly and safely while your store keeps selling.
We connect your store to payments, carriers and parcel lockers, your warehouse, invoicing and national e-invoicing systems such as Poland’s KSeF, plus your marketing tools, so data moves automatically. We also make sure stock levels and orders still match after every nightly sync.
Headless or monolith?
In a monolithic setup, the storefront and backend are a single application, so launch is often faster and, for simple sales, maintenance costs less. In a headless setup, the backend serves data and the storefront is a separate application, so you can change the design, add a second market or launch a mobile app without touching the order logic.
Headless pays off when you have non-standard variants and configurators, several markets, custom pricing rules, connections to internal systems or traffic levels where page speed translates directly into revenue. If you need none of these, we recommend a simpler setup, so you spend your budget on what actually grows sales.
| Criterion | Monolithic platform | Headless (MedusaJS + Next.js) |
|---|---|---|
| Project launch | Fast, using built-in features | Slower, with no catch-up work later |
| Custom checkout logic | Limited by platform settings | Custom workflows and validation on the backend |
| Frontend performance | Depends on the theme and plugins | Full control over page load speed |
| New sales channels | Another store instance | Another client of the same API |
| Integrations with business systems | Through available plugins, within API limits | Directly in code, with custom queues and webhooks |
When every change to a store ships simply and predictably, maintenance costs less for every year the store runs.
The principle behind every project we take on
Scope of work
The 14 specific areas we cover, so your sales keep running smoothly long after launch.
Each of the three has its own root cause and a proven order of fixes, so you know upfront what to expect when we work on your store.
Checkout
The payment has gone through, yet the order still shows as unpaid. Support completes it by hand while the customer is already writing in with a complaint.
The order status is set when the customer returns to the thank-you page. If the customer closes the tab or the gateway notification arrives late, nothing updates that status.
The store backend sets the order status only after the gateway confirms the payment, so the status stays reliable even when the customer closes the tab. We trim the checkout form to the fields needed for shipping, add a pickup point map and save addresses for returning customers.
Platform migration
Each new plugin works around pricing rules the platform can’t handle. Every catalog change means manual work in two places.
The limit sits in the platform’s data model itself, so no setting can remove it, and every extra plugin adds another exception. In a migration like this, you want to keep your search rankings and your complete order archive, and that’s exactly what we secure first.
We start by mapping old URLs to new ones and setting up permanent 301 redirects, and only then move products, customer accounts and the order archive. We rebuild the structured data and the XML sitemap. We switch over during the lowest-traffic hours, with a documented rollback path to the old version.
Multiple markets
Each country has its own store installation. A price change means logging in to as many admin panels as you have markets, and stock levels drift apart between them.
Separate installations mean separate databases. The catalog, prices and stock live in several copies that nobody keeps fully in sync.
We keep one backend and one catalog, and the storefront’s middleware layer detects the market from the URL. We configure currency, tax rates, shipping methods, legal content and pricing rules per country. Your team enters translations in the admin panel.
Engagement models
We agree on the scope at the start and base the quote on clearly defined stages, so you know upfront what you pay for and when.
For companies that are starting to sell online or have decided to move off a platform they’ve outgrown.
For companies with live sales that want to regain development speed after switching vendors.
For companies with their own team that needs extra hands in a specific area or a second pair of eyes.
How we work
We break your sales process down into its parts: catalog, variants, prices, shipping, returns and the systems the store needs to connect to. Before any code is written, you get a concrete list of requirements and risks, so you know what we’ll build and which areas need extra care.
We design the data model, integrations and purchase path, and you approve wireframes of the key views before coding starts. We take design tokens and dimensions straight from Figma.
We work in a separate environment, in one-week cycles. Each stage ends with a working feature you can review, unit and integration tests, and checks at screen widths from 320 pixels up.
We publish the store, configure the domain and SSL certificates with automatic renewal, and set up continuous monitoring that catches issues before customers notice them. After launch, we stay with you for fixes, new features and fast response to requests.
FAQ
When the store has non-standard sales logic, several markets or languages, complex variants and configurators, or integrations with your internal systems. If the catalog is simple and your processes fit a standard platform, we recommend a simpler setup, because headless would then raise costs with no real return.
Yes, as long as the migration is planned. We map old URLs to new ones, set up permanent redirects, move products, customers and order history, and keep structured data and performance in check. We run domain, DNS and certificate migrations during the lowest-traffic window.
Yes. We start with a code, integration and security audit: we check whether passwords or access keys were left in the code, whether form data is validated and whether the server calculates amounts, so customers can’t change them in the browser. After the audit, you get a prioritized list of issues with repair estimates, so you can decide what we tackle first.
Launching a new market includes full local configuration: we set currencies, tax rates, shipping methods and costs, legal content and pricing rules separately for each country, so customers see prices and shipping calculated under their own country’s rules. In a Next.js storefront, we handle language and market in the middleware layer, with correct URLs and hreflang tags for search engines.
Payment gateway integration with local payment methods, Google Pay, Apple Pay and cards, support for pay-later and installment payments, notification signature verification and protection against double charges. On the returns side: an RMA workflow, integration with parcel lockers and fast returns, and statuses your support team can see in the admin panel.
Yes. We manage the server, nginx, auto-renewing certificates, backups, CRON jobs and error monitoring. After launch, development follows the same rhythm as the initial build: request, stage estimate, deployment to a staging environment, release to production.
